AccuBonds vs Ballistic Tips - side by side comparisons

I'm glad to hear that some shooters are having good results with both bullets. I have been using the 180bt for load development in my 300 RUM. One of my reloading buddies had suggested that they would perform identically. With Ballistic tips costing $19 per 50 vs. $32 for Accubonds it pays to use them interchangebly.
